Noble Energy contracts EMAS
for subsea tiebacks in GoM
EMAS AMC has fnalized contracts with
Noble Energy worth a combined $300 million for engineering, procurement, construction, and installation of subsea tiebacks for
the Big Bend, Dantzler, and Gunfint feld
developments in the US Gulf of Mexico.
Project management, engineering, and
procurement are under way in the company’s Houston offce, with fabrication of the
16 subsea structures and stalking and spooling of more than 160 mi (258 km) of line pipe
in progress at the recently upgraded EMAS
Marine Base facility in Ingleside, Texas.
Offshore execution is scheduled for 2015,
using fve of EMAS AMC’s construction vessels including the newbuild, ultra-high tension, deepwater, reel lay and heavy-lift vessel
the Lewek Constellation.
PEMEX elects OneSubsea for
deepwater GoM development
OneSubsea, the Cameron and Schlumberger
company, has won a subsea production systems
contract totaling more than $270 million for the
Lakach deepwater project offshore Mexico. This
is the frst deepwater subsea feld to be developed by PEMEX.
The scope of supply for the seven-well system includes subsea production equipment
and tooling. OneSubsea will also provide installation and commissioning services. Deliveries are expected to begin in June 2016.
Wild Well adds capping
stack in Singapore
Wild Well Control Inc. has added a new subsea well control capping stack to its Singapore
location. The capping stack is Wild Well’s second unit; the frst capping stack unit is located
in Aberdeen. The full intervention system at
each location includes a capping stack, debris
removal shears, hardware kits for the subsea
application of dispersant and inhibition fuids at
a wellhead, and ancillary equipment.
The new 18¾-in., 15,000-psi capping stack
is available for a variety of offshore conditions and designed for subsea use in water
depths to 10,000 ft ( 3,048 m). The system is
maintained in a state of readiness and can be
transported by sea or air.
GE opens subsea technology
GE has opened its $500-million Brazil Technology Center that focuses on subsea oil and
gas technology with special attention to seabed
processing research and development.
Also at the center, GE and BG Group are
combining work on using real-time data to
improve offshore drilling. And, GE and Petrobras are looking into development of improved
seabed oil/water separation. •
McDermott International Inc. has delivered the riser support structure (RSS) for the
INPEX-operated Ichthys LNG Project’s subsea umbilical, riser, flowline development.
The 7,200-ton Ichthys RSS accounts for more than 25% of the total 28,700 tons of
subsea structures that the company is fabricating for the Ichthys project. The RSS
connects the field’s subsea infrastructure to a semisubmersible central processing facility. It is comprised of a tower, more than 328 ft (100 m) tall, with an arch 410
ft (125 m) long also designed and fabricated by McDermott to be installed at a later
date, to support 25 large-diameter flexible risers and dynamic umbilicals. (Photo

Saipem has selected BMT Scientific Marine Services to supply the riser integrity
monitoring systems for the Lula Norte and Lula Extremo Sul developments in the
Santos basin presalt offshore Brazil. The Lula Norte and Lula Extremo Sul will
incorporate BMT’s ROV-Serviceable Subsea Strain Sensor Assembly. This allows for
continuous monitoring and data collection, preserving the absolute bending and
tension measurement while a single sensor is removed and replaced. Riser integrity
monitoring systems measure bending moments and tensile forces in risers in order
to provide end users with an understanding of the risers’ condition. (Photo courtesy
